Raylar has got the goods for the 8.1 if a guy has deep pockets. they just came out with a 2.9L whipple kit that runs at 8-10 lbs of boost but you have to go to forged internals...crank, rods, and pistons. I've read detonation is an issue under boost with stock components, chunks of the pistons fly off because the upper ring lands are too close to the top of the piston.

just doing intake, cam, heads, and exhaust makes a big difference on the 8.1, up to triple digit hp increase.

Ya Raylar is the biggest game in town for the 8.1

Stainless works make the best long tube headers these days too. I have a spare 8.1 with 1000 KMS sitting in my garage , had it for years!! Gunna send Raylar my spare intake for a little polish job. I wish the Dollar wasn't so lousy I want headers too. Lol

Had an '01 crew cab 8.1. Great truck. My old man had a '00 6.0l at the same time and we got identical mileage. Ended up trading it on a Duramax that served me well, too.

One of my best buddies bought a brand new loaded 01 2500 CCSB 8.1L/ally in January 02, I think he paid 38k for it. Was a pretty great truck, lifted from day one and he put 405,000km on it with no engine work required. Thirsty as hell, and went through a tranny, couple t-cases, bunch of front end parts, and a weird electrical gremlin that would randomly drain the battery overnight. Stock to stock it'd beat my 04 F350 6.0 by half a truck length in the 1/4 mile. Then about 6 years ago, he got a used 03 8.1 dually and its a dog, even after a custom hptuners tune. He still likes it, can sit for months and then any day of the year you can hook up a booster pack and be on your way in minutes.

I love my '05 8.1L, had if for 8yrs now I think and it has about 160k on it. Had to redo the front end last year, but other than that it has been pretty solid. Just tires and batteries, for some reason lots of batteries (maybe because I don't drive it much, and maybe because they were originally moto-master batteries). Best empty mileage was around 13mpg, and when loaded with sleds it is somewhere usually around 10mpg. It has cold air intake and some custom exhaust work, and have thought lots about getting a tune but haven't done it yet.

Oh yeah, another fault seemed to be the amount of torque generated would twist the frame just enough that the cab would twist independent of the box and exhaust hangers kept breaking (at least that’s what I think it was), so I put in some braided exhaust line between the two and I’ve never had an issue since.

It's not that the cab moves, as the engine and exhaust is mounted the hole way to the frame


But what happens is the engine to pipe mounts are solid and the only give is the rear rubber hangers

The older 350 vortex had a doughnut and spring -bolt setup that could flex, and where bullet proof

I also had an '01 8.1l crew cab - still kick myself for selling it. Love to find anther one in the same shape. 5000km always = 1l of oil burned, but never had a serious problem with it.

Tough on fuel when towing or when you have a heavy foot, but then again, the fuel economy for any diesel truck I've owned is nothing to brag about either.

For a few years, chev. made a 2500 avalanche with the 8.1l in it. Took one for a test drive just for fun - not practical for me, but a ton of fun. Tons of power and snakey in the short chassis.

that's the only real grief I've had with mine, it seemed no battery would last more than 2 or 3 years. switched to an optima the last time and it has lived the longest so far. as for mileage, best empty mileage I've got was 17 by keeping it at 100km/hr or less. my pa had a 6 litre in a 1500 HD and we went to the city and kept track of our mileage, my 8.1 used one litre more fuel than his over the same distance. loaded them both up with junk we bought at the auction and mine got 4 mpg better than him on the way home.

I'm just treating it as a cheap puller! Ya it sucks gas but what gas job doesn't when hooked to 10000#

I used the father in laws Toyota last year with the v8. I spent $375 one way to Kelowna

I'm sure this thing will too but more hp

Bought complete Amsoil oil swap for diffs, tcase, tranny and engine. So will see if that helps a bit but not holding out much hope for huge gains. But I wanted to change all fluids anyway.

Just picked this bad boy up. I've been looking for almost a year for one of these things in decent shape. . 115k don't think there is a scratch on it no rust lt trim she's a beauty. It's gonna be used exclusively for pulling my rv.

 

[DirtLUmp]

Anybody interested in a free topper?

Is that Wes lecktimin's from eckville ??

 

[DirtLUmp]

No I picked it up from a kid in Calgary. He said he bought it from a guy in lacombe about 4 years ago for his window washing business. It's been parked for the last 3 years.

 

[tex78]

Huh, he has a truck just like it



Looks good

 

[DirtLUmp]

So you know where I can get a good tune in rocky Tex?

 

[tex78]

Ya Travis or mike from Edwards, would say more so mike as it's a gas and not a diesel

Diesel then Travis is the man

Awesome !! Another cool kid!! My brother bought one too for a go to the dump truck. Seams like more ECSB out there!
What make is the topper?

 

[OVERKILL 19]

The paint match fender flares sure look the best IMO. I've been searching for white ones. Bought a black set for $100 the other day just to help block some of the road grime.
